Washing machine for comestibles



Filed March 26, 1927 /n v en for I Haber/- Spa/dd Patented June 9, 1931 UNITED STATES PATENT OFFICE WASHING MACHINE For. COMES'IIBLES Application filed March 26, 1927, Serial No. 178,603, and in Germany December 20, 1926.

The invention relates to washing machines for comestibles, and in addition for removing the salt from salted fishes or salted meats.

The invention consists of a washing machine for'comestibles in which a tiltable receiver is provided with an agitator shaft extending up through the bottom thereof into the interior, a frame upon the bottom of said receiver, said frame supporting asieve bottom, a motor mounted on the bottom of the receiver and operatively connected to the lower end of the shaft below the bottom of the receiver, an agitator element having a central hub detachably mounted upon the upper end of the agitator shaft to rotate therewith,

- a water discharge pipe connected to the receiver, an upwardly extending telescoping pipe connected to said discharge pipe, and

a U-shaped pipe connected to the upper end its highest point.

The subject matter of the invention is illustrated' in the accompanying drawings by way of example in which Fig. 1 is a side elevation of the machine.

Fig. 2 is a vertical section on the line A-B of Fig. 1.

Fig. 3 is a plan view of the machine, and

Fig. 4 is a plan of the machine with the agitator element and sieve bottom' removed.

-Like characters of reference indicate corresponding parts in the difl'erent views. The washing machine consists of a frame a, provided at its upper end with bearings b. Trunnions o are disposed in these bear- 25 washing ings 6, whereby the swingable receiver d is supported.

On the underneath side of the bottom, a socket e is provided, which may, for instance, be fastened to the receiver by welding. A bushing f is inserted into this socket e from above, this bushing being locked against rotation. The bushing 7 receives the shaft g of the agitator element, resting with its collar h upon the upper end of the bushing f. The shaft g of the agitator element is packed by means of a stuffing-box z'. The shaft 9 of the agitator element carries a worm-wheel 70 at its lower end which meshes with a worm mounted with their hub t.

blades 8 are provided at their lower ends with of the telescoping pipe and having a vent at f Z keyed to the shaft of an electric motor m. The electric motor m is mounted upon a plate n, secured to the underneath side of the receiver'bottom, for instance, by welding.

A frame is slipped down over the bushing f, and comprises a hub 0 and radially disposed arms ;v, these arms being carried to the wall of the receiver d. A sieve bottom 9 issupported by this frame.

The upper end 1' of the agitator element shaft 9 is preferably square in cross section. Upon this end 1*, the agitator blades 8 are The agitator extensions 8 extending almost to the wall of the receiver (Z.

The hub t has at its upper end a handle 4 for handling and lifting the agitator ele-' ment. The hub 25 may be operatively mounted in any other suitable manner upon the shaft 9 so as to rotate therewith.

On one trunnion o of the receiver d a worm wheel u is mounted which meshes with a worm a), which can be revolved by means of the crank handle w. An opening :0 with a drain cock 1 is provided at the bottom of the receiver and an overflow pipe 2 is furthermore connected to the receiver bottom.

Into the upper end of the overflow pipe, an inverted U-shaped pipe 2 is telescopically inserted, said U-shaped pipe having an opening 3 at its top for preventing it from acting as a syphon. By altering the position of the, U-shaped pipe 2, the water level in the receiver d can be adjusted. 5 is a cock for 5 the water supply.

The washing water contained in the receiver can only flow off as long as its level is above the U-shaped pipe 2. The water in the overflow pipe 2 exerts a counter pressure upon the water in the receiver d, so that the same cannot force the material, for instance, salad leaves, against the openings of the sieve g, and obstruct the same, thereby preventing further working of the machine.

The mode of action of the machine is as follows:

In the position illustrated in Figs. 1 and 2, the receiver 03 is charged with the material to be washed. By means of a cock 5, situ- 1m ated above the rim of the receiver, water is thereupon admitted and the agitator element set into action. The material is moved in the water by means of the blades 8 and thereby freed from sand and other foreign matter adhering thereto.

The sand sinks to the bottom and is passed through the openings of the sieve 9 into the pipe 2 and discharged with the overflowing water. The dischar ed water can be continually replenished %)y fresh water.

By adjustment of the telescopic pipe 2, the quantity of discharged water can be adapted to the quantity of fresh water supplied. The material is treated until the water flowving from the pipe 2 is clear showing that sand and mud have been completely removed from the material. The water supply is then cut off and the cock y opened to drain the water completely from the receiver (1. The receiver is then swung over by means of the crankhandle w,.the worm 4: and the worm-wheel u when the material will drop out of the receiver.

I claim:

In a washin machine for potatoes, vegetables, fruit, sa ted meat, salted fish and other food substances, the combination with a tiltable receiver, of an agitator shaft extending up through the bottom of the receiver into the interior thereof, a frame upon the bottom of said receiver, said frame supporting a sieve bottom, a motor mounted on the bottom of the receiver and operatively connected to the lower end of the shaft below the bottom of the receiver, an agitator element having a central hub detachably mounted upon the upper end of the agitator shaft to rotate therewith, a water discharge pipe connected to the receiver, an upwardl extending telescoping'pipe connected to send discharge pipe, and a -sha. ed pipe connected to the upper end of the te escoping pipe and having a vent at its highest point.

In testimony whereof I have aflixed my signature.
